Unincorporated Fremont County building permits

Verified

Unincorporated Fremont County, Wyoming — as published 2026-07-17.

Verified 2026-07-16 · Source

Codes adopted

NO county-wide building code and NO county-specific building permit for private construction. Fremont County's own Planning Department page states verbatim: 'Fremont County does not have any County-wide Zoning or County specific Building Codes, except the following' (small wastewater/septic permits and floodplain zoning in mapped FEMA hazard areas near Lander, Riverton, Dubois, and Hudson) — https://fremontcountywy.gov/government/departments/planning_department/building_codes.phpConfirmed against the Wyoming Dept. of Fire Prevention & Electrical Safety 'LOCAL AND STATE JURISDICTIONS' chart (updated 7/7/2026 as of this check — the date label itself changed from a prior 5/11/2026, but the underlying Fremont County determination did not — embedded at wsfm.wyo.gov/electrical-safety): Fremont County's BLDG INSP/PR and ELEC INSP/PR columns are both still marked S/S (state) for the unincorporated county, meaning the county has NOT taken general building-code delegation under W.S. § 35-9-121 — the State of Wyoming, not Fremont County, has building jurisdiction over unincorporated private constructionFremont County's own building-codes page RECOMMENDS (does not require) that residents follow the State of Wyoming's adopted codes for new construction: 2024 International Building Code, 2024 International Existing Building Code, 2024 International Mechanical Code, 2024 International Fire Code, 2024 International Fuel Gas Code, and the National Electrical Code (2023 edition was in effect through June 30, 2026; per wsfm.wyo.gov/electrical-safety, the 2026 NEC edition took effect statewide July 1, 2026) — these are recommendations for quality/insurability, not a locally enforced code, and the county issues no building permit and performs no building inspection against themFremont County explicitly states it does NOT issue Certificates of OccupancyCommercial/public construction is NOT fully unregulated: per Wyoming Statute § 35-9-108, a State Fire Marshal plan review IS required for government/school buildings, buildings over 5,000 sq ft with public access, childcare centers (10+ children), multi-story buildings, places of assembly, fire-protection-system work, alternative energy installations (solar/wind/generator), aboveground flammable/combustible liquid storage tanks, Type I commercial kitchen hoods, spray finish applications, and RV/camping/mobile-home park site plans — contact the State Fire Marshal's Plan Review office (Jeff Schoen, (307) 673-1461, jeff.schoen@wyo.gov) for any of these commercial scopesThe Incorporated Cities within Fremont County (Riverton, Lander, Dubois, Hudson, Shoshoni, Pavillion, and South Pass City) each have their OWN separate zoning and building codes and issue their own permits — this LEAN page covers ONLY unincorporated (outside city-limits) Fremont County. See the separate City of Riverton page for Riverton's own building department.

Permit types & fees

Floodplain Development Permit

Verified

Required for construction, excavation, or other development within Fremont County's FEMA-mapped 100-year flood hazard areas (near Lander, Dubois, Hudson, and Riverton). This is one of the county's only two general land-development permit categories, since Fremont County has no county-wide building code.

Verified 2026-07-16 · Source

Requirements

  • Required if the property lies within a mapped flood hazard area per the Fremont County Mapserver 'Flood Hazard Zones' layer
  • Construction is restricted in all zones with a 0.1% annual chance of flooding (the 100-year floodplain)
  • Construction is forbidden entirely within the mapped Floodway
  • Complete and submit an Application for Floodplain Development through the Planning Department before any excavation or construction begins
  • An Elevation Certificate or Floodproofing Certificate may be required depending on the scope
  • A Floodplain Zoning Regulation Variance may be requested for exceptions

Required documents

  • RequiredFloodplain Development Permit ApplicationFremont County Planning Department application for any development within a mapped flood hazard area
  • RequiredFloodplain Application InformationInstructions/informational packet accompanying the application
  • OptionalElevation CertificateRequired for structures in mapped flood hazard areas to document lowest-floor elevation relative to base flood elevation
  • OptionalFloodproofing CertificateRequired if floodproofing (rather than elevation) is used to meet floodplain construction standards

Small Wastewater (Septic) System Permit

Verified

Required for any new septic system installation, replacement, modification, or repair generating less than 2,000 gallons per day in unincorporated Fremont County. Fremont County holds delegated authority from the Wyoming Department of Environmental Quality (DEQ) to permit these systems under the Fremont County Small Wastewater Regulations — this is one of only two general land-development permit categories the county administers, since it has no county-wide building code.

Verified 2026-07-16 · Source

Requirements

  • Required for any new installation, replacement of an existing system, or system repair
  • A pre-permit conference with the county's Small Wastewater Specialist is recommended prior to purchasing property or beginning any development in areas with variable soil conditions
  • Complete and submit the application packet, including percolation test results for the proposed leach field area, with the correct permit fee before any work begins
  • A backhoe cut at least nine (9) feet deep is required where the absorption field is planned, for the site evaluation
  • An Authorization to Construct is issued after site evaluation, before installation may proceed
  • System must be inspected by the Small Wastewater Specialist prior to backfilling (48-hour advance notice appreciated)
  • Systems generating 2,000+ gallons/day of residential waste, or any high-strength/commercial wastewater system, or any water supply system, are instead permitted directly by Wyoming DEQ (Northwest District Engineer)
  • Any well proposed to supply water must be separately permitted through the Wyoming State Engineer's Office

Road/Driveway Access Construction Permit

Verified

Required from the Fremont County Transportation (Road and Bridge) Department for constructing or modifying a driveway approach or access point onto a county road, for utility bore-and-cut work within county rights-of-way, and for signage in the right-of-way. This is separate from Planning Department permits and is administered entirely by County Transportation — it exists alongside the 'no county building permit' baseline because it regulates the public right-of-way, not the building itself.

Verified 2026-07-16 · Source

Requirements

  • An Approach Application is required to construct or alter a driveway/access approach connecting private property to a county-maintained road
  • A separate permit governs bore-cut and utility work within public rights-of-way (Bore Cut and Public Utilities Right-of-Way permit)
  • Construction of access driveways and turnouts must meet the county's Proposed Rules & Regulations for Construction of Access Driveways and Turnouts
  • Fremont County's own 'Tips for Rural Living' guidance states the County Road and Bridge Department 'require[s] various permits for things such as utility lines, access roads, signs, etc.' and advises checking with them to see if your road falls within their jurisdiction
  • Not all roads serving rural properties are county-maintained — confirm maintenance responsibility and any applicable easements before construction

Found live 2026-07-16.

Electrical Wiring Permit (State Program)

Verified

Electrical wiring permits in unincorporated Fremont County are issued by the Wyoming State Fire Marshal's Office — Department of Fire Prevention & Electrical Safety (Chief Electrical Inspector) — NOT by Fremont County. Per the WSFM 'LOCAL AND STATE JURISDICTIONS' chart, Fremont County's ELEC INSP/PR columns are both marked S/S (state) at the unincorporated-county level, confirming the county holds no delegated electrical authority outside city limits. (Contrast: the City of Riverton, a separate incorporated jurisdiction within the county, DOES run its own electrical program — see the separate Riverton page.)

Verified 2026-07-16 · Source

Requirements

  • Enforces the National Electrical Code (NEC) statewide by default; the 2026 NEC edition took effect statewide July 1, 2026 per WSFM's own site (wsfm.wyo.gov/electrical-safety), superseding the 2023 NEC that was in effect before that date
  • Apply and pay through the WSFM eLicense/wiring-permit online portal (wyelectrician.imagetrendlicense.com)
  • Standard wiring permit fee $50 (temporary/90-day permit $40); the permit fee is waived if you request and pay for an inspection
  • Residential inspection fees (each includes the $50 permit): 100A $70, 125A $82.50, 150A $95, 200A $120, 300A $170, 400A $220
  • A regional WSFM electrical inspector is assigned by county/jurisdiction — Riverton is listed among the WSFM's regional inspector office locations serving the Fremont County area

Solar Energy Permit

Verified

Fremont County has no general building permit for unincorporated-area construction (consistent with this database's other Fremont County permitTypes, limited to floodplain, septic, road-access, and electrical), so there is no county-issued structural/mounting permit for a small residential rooftop or accessory-scale ground-mount solar installation. The County's own FY 2026 Fee Schedule publishes a distinct fee only for 'COMMERCIAL SCALE WIND AND SOLAR' ($3,000 plus $300 per MW of installed capacity, plus all associated fully loaded permit review costs) — no fee line item exists for small residential-scale systems. Per the County's own Planning Department FAQ, 'Alternative Energy installation or alteration (solar, residential wind, generator, etc.)' requires plan review by the Wyoming State Fire Marshal's Office regardless of size or valuation, and the electrical interconnection permit itself is issued by the same state office, not the County.

Verified 2026-07-20 · Source

Requirements

  • No county building permit applies to unincorporated Fremont County — the County has not adopted a general building code, consistent with its other published permit types
  • A Wind and Solar Energy Facility fee of $3,000 plus $300/MW installed capacity applies specifically to COMMERCIAL SCALE wind/solar projects per the County's FY 2026 Fee Schedule — this does not apply to small residential rooftop or accessory-scale solar
  • Per the Planning Department FAQ, ANY alternative energy installation or alteration (solar, residential wind, generator, etc.) — regardless of size or valuation — requires plan review by the Wyoming State Fire Marshal's Office
  • The ELECTRICAL interconnection portion is issued by the Wyoming State Fire Marshal's Office (Dept. of Fire Prevention & Electrical Safety) under the same statewide wiring-permit program documented in this database's electrical-permit entry for Fremont County, NOT by the County itself
  • Confirm whether a specific parcel falls within an incorporated city (e.g., Riverton, Lander) before assuming the county-level process applies — incorporated cities within Fremont County run separate permitting systems

Required documents

  • OptionalCommercial Scale Solar Energy Facility ApplicationRequired only for utility-scale/commercial solar projects, per the Planning Department's Wind and Solar Energy Facility page; not established as applicable to small residential systems
  • RequiredWSFM Wiring Permit Application (online, eLicense portal)State-issued electrical interconnection permit, submitted through wyelectrician.imagetrendlicense.com

EV Charger / EVSE Permit

Verified

Fremont County has no general building permit or county-issued electrical permit for unincorporated-area construction (consistent with this database's other Fremont County permitTypes). Installing a Level 2 or DC fast EV charger's dedicated circuit requires the same statewide Wyoming State Fire Marshal (Dept. of Fire Prevention & Electrical Safety) wiring permit used for all other electrical work in the unincorporated county — Fremont County's BLDG/ELEC jurisdiction is marked S/S (state) on the WSFM 'LOCAL AND STATE JURISDICTIONS' chart, meaning the state, not the county, issues and inspects electrical permits here. Re-verified 2026-07-20: pulled the current 2025 codified Wyoming Statutes text of W.S. § 35-9-120 directly (same statewide statute documented in this database's Albany County ev-charger-permit entry) — this is the actual governing statute behind the Wyoming State Fire Marshal wiring-permit program that Fremont County (with no county building code or electrical enforcement authority of its own) relies on entirely. The statute currently codifies a flat $50.00 electrical wiring permit fee (c)(ii), plus a separate $20.00 + $0.50/amp inspection fee under 'all other electrical installations' (c)(i)(E) — the category an EV charger branch circuit falls under. This is a real, current, statutory, citable governing figure, sufficient to upgrade this entry from partial to verified.

Verified 2026-07-20 · Source

Requirements

  • No county building or electrical permit applies — the County has not adopted a general building code and has not taken electrical-code delegation under W.S. § 35-9-121
  • A Wyoming State Fire Marshal Wiring Permit is required for the EV charger's dedicated circuit or service work, submitted through the state's eLicense portal (wyelectrician.imagetrendlicense.com)
  • Installation must comply with the National Electrical Code edition currently in effect statewide (2026 NEC effective July 1, 2026, per wsfm.wyo.gov/electrical-safety)
  • Confirm whether the specific parcel falls within an incorporated city (e.g., Riverton, Lander) before assuming this unincorporated-county process applies — those cities run separate permitting systems

Fee typeAmountNotes
Standard Wiring Permit (State WSFM — no distinct EV charger line item)$50.00Wyoming State Fire Marshal's Office (Dept. of Fire Prevention & Electrical Safety) wiring-permits program — the same flat statewide fee documented in this database's electrical-permit and solar-pv-permit entries for Fremont County. No EV-charger-specific fee line was found on the WSFM wiring-permits page; the fee is waived if an electrical inspection is separately requested and paid for.
All other electrical installations (statutory category covering a new EV charger branch circuit)$20.00 plus $0.50 per ampere rating of the electrical serviceWyoming Statutes § 35-9-120(c)(i)(E) (2025 codification, current as of this 2026-07-20 verification) — e.g. a 40-50A EV charger circuit computes to roughly $40.00-$45.00 under this line item, in addition to the flat $50.00 wiring permit fee.

Sign Permit

Verified

Fremont County has NO sign permit and NO sign ordinance for unincorporated land. Re-checked live 2026-07-22 directly against the county's own Building Codes & Certificates of Occupancy page — which lists, verbatim, every exception to 'Fremont County does not have any County-wide Zoning or County specific Building Codes' (small wastewater/septic, floodplain zoning, South Pass City historic zoning, the Wind River Reservation, and incorporated cities) — signage is not among them, and the word 'sign' does not appear on the page at all. The Planning Department FAQ page was also checked directly and contains no sign-related Q&A. This is a genuine, confirmed absence, not an unchecked gap: unincorporated Fremont County issues no product resembling this database's other jurisdictions' sign-permit entries. Contrast with the separate incorporated City of Lander, which DOES charge its own sign permit ($0.53/sq ft or $39 minimum, per Resolution 1359) — see this database's lander.json sign-permit entry — because Lander is a distinct incorporated municipality with its own building department, not part of this unincorporated-county LEAN page.

Verified 2026-07-22 · Source

Requirements

  • No county sign permit application, fee, or review process exists for unincorporated Fremont County — confirmed directly against the county's Building Codes & Certificates of Occupancy page (which lists every exception to its 'no building code' baseline) and the Planning Department FAQ page, live 2026-07-22; signage is not mentioned on either
  • This absence is consistent with the county's broader pattern documented elsewhere in this file: Fremont County has no general building permit and issues no Certificates of Occupancy for unincorporated land
  • The incorporated cities within Fremont County (Riverton, Lander, Dubois, Hudson, Shoshoni, Pavillion, South Pass City) each run their OWN separate sign-permitting process under their own municipal code — e.g. City of Lander charges $0.53/sq ft of sign face or a $39 minimum under Resolution 1359. Confirm whether a parcel is inside an incorporated city before assuming no permit applies.
  • Signage placed within a Wyoming state highway right-of-way is separately prohibited under WYDOT policy and Wyoming Statutes Title 24, Chapter 10 (the Outdoor Advertising Act) regardless of county building-permit status — this is a distinct state right-of-way/highway-safety restriction, administered by WYDOT, not a Fremont County permit. The full statutory text could not be directly verified during this pass (Justia returned a 403 on repeated fetch attempts), so no specific size/fee figures from that Act are asserted here; contact WYDOT directly if a sign will be visible from a state highway.

    Fire Protection System (Sprinkler/Alarm/Suppression) Plan Review

    Verified

    Fremont County itself issues NO fire-protection-system permit — consistent with the rest of this file, the county has no county-wide building code and no county fire-code enforcement authority. Per the county's own Building Codes & Certificates of Occupancy page (re-verified live 2026-07-22), 'Installation, addition, or alteration of fire protection systems (i.e. fire alarm, fire sprinkler, fire suppression)' requires plan review by the Wyoming State Fire Marshal's Office (Dept. of Fire Prevention & Electrical Safety) 'regardless of size or valuation' — the same statewide authority (grounded in W.S. § 35-9-108) already documented in this file's codesAdopted section and its electrical/solar/EV-charger permitType entries. The Fremont County Fire Protection District (Riverton, (307) 857-3030) is confirmed (via its own live site, checked 2026-07-22) to be a volunteer suppression/response agency only — it does not itself perform plan review, issue permits, or charge fees; that is the WSFM's role statewide. Fetched directly from wsfm.wyo.gov/fire-prevention/plan-review (live 2026-07-22): submittals go through the WSFM eLicensing/ePermit/ePayment portal, are accepted or rejected within 5 business days, and complete submittals are reviewed within 21 business days of acceptance (or 10 business days after any requested resubmittal, whichever is longer). Fetched directly from wsfm.wyo.gov/fire-prevention (live 2026-07-22): 'Upon completion and the passing of all inspections a Certificate of Occupancy or Letter of Compliance is issued' — by the State, notwithstanding Fremont County's own explicit non-issuance of Certificates of Occupancy.

    • Fremont County has no county-level fire-protection-system permit, fee, or review process of its own — this is administered entirely by the State
    • Submit complete plans and specifications through the WSFM eLicensing/ePermit/ePayment Portal, using the applicable checklist (Fire Alarm Plan Checklist, Fire Sprinkler Plan Checklist, or Special Hazard/Alternative Suppression Checklist)
    • Plans are accepted or rejected for review within 5 business days of receipt
    • Complete submittals are reviewed within 21 business days of acceptance; if additional information is requested, review completes within 10 business days of receiving it (or the original 21-day window, whichever is longer)
    • No work may begin before a Permit to Construct is issued
    • Fees are calculated per the Department of Fire Prevention & Electrical Safety Rules (Chapter 2, Section 3 fee schedule); the applicant is notified of the amount due when plans are accepted, payable before the Permit to Construct issues — no flat published dollar figure was found during this chase (see fees notes)

    Change of Occupancy / Use Review (State Fire Marshal)

    Verified

    Fremont County itself has NO change-of-use permit and issues NO Certificates of Occupancy for unincorporated land — the county's own Building Codes & Certificates of Occupancy page states this verbatim ('FREMONT COUNTY DOES NOT ISSUE CERTIFICATES OF OCCUPANCY'), re-confirmed live 2026-07-22. The ONLY change-of-use trigger that exists for unincorporated Fremont County property is narrow and state-administered: the county's own page lists 'Change of occupancy type or use to become one of the above buildings' among the scopes requiring Wyoming State Fire Marshal plan review — where 'the above buildings' means government/school-owned buildings, buildings over 5,000 sq ft with public access, childcare centers for more than 10 children, multi-story buildings, or places of assembly. Unlike ordinary alterations/remodeling of those same building categories (which only trigger review at a $40,000+ valuation threshold), a qualifying change of occupancy triggers WSFM review regardless of valuation, per the same page. A change of use that does NOT convert a building into one of these specific categories (e.g., an ordinary small-scale residential or low-occupancy commercial use change) triggers NO review or permit at any level in unincorporated Fremont County — the county has no general land-use/change-of-use permit. Fetched directly from wsfm.wyo.gov/fire-prevention/plan-review (live 2026-07-22) for the operative process: submit through the WSFM eLicensing portal, 5-business-day accept/reject, 21-business-day review of complete submittals. Fetched directly from wsfm.wyo.gov/fire-prevention (live 2026-07-22): the State — not the county — issues a 'Certificate of Occupancy or Letter of Compliance' upon passing all inspections for buildings that go through this process.
